Feinwerkbau Air-Pistol Cylinder

General information on Feinwerkbau compressed air tanks.

The compressed air tanks from FEINWERKBAU fall under the Pressure Tank Ordinance, but do not require approval
(e.g. by TÜV, etc.). The manufacturer must ensure the safety of the compressed air tanks.
For this reason, the service life of the compressed air cylinder has been limited to 10 years. After that, they must be disposed of safely
become. If the compressed air tanks are to be used for a period longer than 10 years, FEINWERKBAU
safety can no longer be guaranteed.
The compressed air tanks are made of a special, very high-quality aluminum alloy.
Nevertheless, the material is subject to an aging process, i.e. it can become brittle under certain circumstances. The high loads
due to the filling pressure of 200 bar (for comparison: a car tire is filled to approx. 3 bar), as well as the alternating load between
The full and empty state of the container can lead to the material structure being subjected to the stresses of a
service life of more than 10 years has not increased.
An often mentioned overhaul or “TÜV test” is not possible to extend the service life of a compressed air tank
to extend.

an inspection of the compressed air tanks was prescribed after 5 years. This deadline was set by FEINWERKBAU
10 years extended – after this useful life the container should be disposed of safely.
